In a fanfiction, Sakura could be ill with a mysterious disease. Sasuke, who has come to care for her deeply, is worried sick. He travels far and wide to find a cure, consulting various healers and even delving into some dark arts. His worry is palpable as he constantly thinks about her and how he can't bear to lose her.
Maybe Sakura goes on a dangerous mission alone. Sasuke, who has his own sources of information, starts to worry. He remembers all the times she has been strong but also vulnerable. So, he decides to follow her at a distance to make sure she's safe. When she gets into a tough fight, he steps in at the last moment to save her, his worry for her driving his actions.
One scenario could be in a post - war situation where Sakura is overworking herself in the hospital. Sasuke, being worried, secretly watches over her. He might leave little gifts or notes for her to find, showing his concern without directly approaching her as he's still not used to expressing emotions openly.
Another situation could be that they are on a mission to rescue some hostages. The enemy has set up a complex ambush. Sasuke is hit by a barrage of shuriken and kunai, getting multiple cuts and bruises. Sakura tries to heal him but is then attacked herself. She gets a head injury which affects her ability to use her medical jutsu effectively, leaving them both in a very vulnerable state.
One example could be a fanfiction where Snape secretly follows Harry during a dangerous mission outside Hogwarts because he's worried. He uses his skills to protect Harry without Harry realizing it, showing his hidden care.
Well, perhaps in a fanfiction, Sasuke could cry for Sakura when he discovers a deep secret she has been hiding. Maybe it's something that makes him understand her on a whole new level, like a hidden pain she has endured all this time for his sake. This newfound understanding could stir such strong emotions in him that he can't hold back his tears.
When Sasuke is worried about Sakura in fanfiction, it can bring them closer. His worry shows that he cares, which is a big step for Sasuke. Sakura, in turn, feels more connected to him as she realizes his concern. This can lead to more open communication between them.
An interesting scenario could be when Sasuke donates blood for Sakura who is in need during an emergency operation. It shows his selfless side towards her. Another could be Sakura using her new - found medical jutsu to heal Sasuke's old wounds, both physical and emotional, as they talk about their past traumas in the quiet of the hospital room.
Well, sometimes in this kind of fanfiction, Sasuke insults Sakura when he's feeling pressured by his own dark path. He might see Sakura as a reminder of the normal life he can't have. For example, he could say 'Your naive dreams are nothing but a waste of time, Sakura.' It could also be that he's trying to protect his image among his enemies and thinks that by insulting Sakura, she'll be less of a target.
Often in these fanfictions, Sasuke gets jealous when Sakura is training with someone else who is really good at a particular skill. Let's say she's training with Rock Lee to improve her taijutsu. Sasuke might see how dedicated Lee is to helping Sakura and get jealous. He may think that he should be the one helping her. And then he might try to interrupt their training sessions or show off his own skills in front of them to prove that he's better, all because of his jealousy.
Sakura might use her intelligence to solve a complex problem that even Sasuke couldn't figure out easily. For instance, she deciphers a mysterious code or finds a way to bypass a dangerous trap. This would show Sasuke that she is not only strong physically but also mentally, and he would be impressed.
One interesting scenario could be that Sakura tries to cook for Sasuke during the sleepover. Since she has improved her cooking skills over the years, she wants to surprise him with his favorite dishes. Sasuke, on the other hand, might be a bit hesitant at first but then really enjoys the food.
In some fanfictions, Sakura has a spiritual journey. She might go on a pilgrimage or study under a wise sage. During this process, she gains inner peace and self - discovery, which allows her to look at her relationship with Sasuke in a new light and finally move on.
